Combine in a bowl all the ingredients for the patties except the oil. Mix well. Form into a ball (2" diameter), then, slightly flatten. This recipe will make 10 patties. Fry in in medium-low heat on both sides until done. Do the same to the rest. Place in a serving platter. Set aside.

Drain well the canned button mushrooms. Slice into to two.

In a small sauce pan, bring the water to boil over medium fire. Pour in the mushroom gravy powder. Stir using a wire whisk. Cook until slightly thick. Add the button mushrooms. Mix. Remove from fire. Pour over the patties immediately.
